Output EU doesn't show properly on panels

[Kerem204]

I'm using EnergyControl 1.12.2-0.2.8 and the counter sensor card shows only the period while in the second and third slot, and while it's in the first slot, instead of showing the output value it shows "msg.ec.InfoPanelOutputEU". There's no checkboxes either to show/hide the period in the panel UI.

Please let me know if this is something I can fix myself, because the same thing happens with the output on reactor sensor cards, but it worked properly before.
